Earlier quoted context omitted.
An ad for "18 YEAR OLD WOMEN" is scary? They don't bite. It seems generic not really weird.

But mostly F-droid, which has Newpipe. Both excellent and reliable and shite-free.
I really don't get app stores. How did they convince everyone to install so much spy and adware?
